New Clooney Movie "The American" Not Mainstream Enough For Success?

Anton Corbijn's The American (Focus Features, 9.1) will screen for press two days before it opens on Wednesday, September 1st. My sense is that Corbijn has made an exquisite-looking, almost arty-type film, but it may not be juicy enough for Joe Popcorn. My only other comment is that George Clooney's hair is too short in this thing. It looks a little Third Reich-y, too intense, something.
